             Bug #: 51948
           Summary: [OOP] Rejects valid: Polymorphic arguments in
                    MOVE_ALLOC
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Keywords: rejects-valid
          Severity: normal
          Priority: P3
         Component: fortran
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: burnus@gcc.gnu.org


The following fails at move_alloc with bogus errors. The second example is
based on the example from
chapter09/burgers_factory_f2003/periodic_6th_order.F90 in the book
http://www.cambridge.org/rouson

type t
end type t

contains
  function func(x)
    class(t), allocatable :: x(:), func(:)
    call move_alloc (x, func)
! FAILS: Error: the 'from' and 'to' arguments of 'move_alloc' intrinsic at (1)
must have the same rank 0/1
  end function

  function func2(x)
    type(t), allocatable :: x
    class(t), allocatable :: func2
    call move_alloc (x, func)
! FAILS: Error: 'to' argument of 'move_alloc' intrinsic at (1) must be a
variable
  end function
end
